Two different conducting objects, initially separated, are connected by a conducting wire. When the wire is removed, can you conclude that the two objects: (a) carry the same net charge; (b) are at the same potential; (c) have the same charge and the same potential; or (d) have neither the same charge nor potential? Explain.

Energy is the ability to do work which measures what

You add 800 ml of water at 20c to 800 ml of water at 80c what is the most likely final temperature of the mixture ? a. 100c b. 60c c. 25 c d.50c

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
